Deployment ScenariosThe EX8216 modular switch is designed for a variety of data center deployments, providing a high-performance, high-density core platform that reduces cost and complexity while improving overall scalability and offering carrier-class reliability.

Populated entirely with 10-Gigabit Ethernet line cards, a single EX8216 Ethernet Switch can accommodate up to 128 high-speed, line-rate uplinks from access-layer devices such as EX4200 VZLWFKHV�GHSOR\HG�LQ�9LUWXDO�&KDVVLV�WRS�RI�UDFN�FRQĆJXUDWLRQV��delivering a highly scalable solution that can support more servers with fewer actual switches. A single EX8216 chassis can also support up to 768 Gigabit Ethernet ports to serve as a highly effective, end-of-row server access switch.

The high Gigabit Ethernet and 10-Gigabit Ethernet port densities on the EX8216 enable the consolidation of aggregation and core layers, dramatically simplifying data center architectures and reducing total cost of ownership (TCO) while lowering power, space, and cooling requirements.

Architecture and Key ComponentsJuniper Networks EX8200 line of Ethernet switches, including the EX8216 and EX8208, share a number of distinct architectural elements. The Routing Engines employed by these switches run JUNOS Software, which processes all Layer 2 and Layer 3 protocols and manages individual chassis components, while the switch fabrics provide the central crossbar matrix through which all data traffic passes.

The EX8200 line cards, which are common across all EX8200 platforms, include ASIC-based packet forwarding engines—the EX-PFE2—that process network traffic at wire rates, as well as a line-card processor that provides scalable local control.

The EX8216 architecture was designed for very large data center deployments, with no head-of-line blocking, a single-tier low-latency switch fabric, efficient multicast replication handling, and deep buffering to ensure performance at scale. The EX8216 chassis midplane distributes the control and management plane signals over independent paths to the various system components and distributes power throughout the system. Data plane signals pass directly from the EX8200 line cards to the EX8216 switch fabric modules via a unique connector system that provides unparalleled signal quality for future generations of fabric technologies.

To maintain uninterrupted operation, the EX8216 switch’s two fan trays cool the line cards, Routing Engine, and switch fabric modules with redundant, variable speed fans. The EX8200 line’s power supplies convert building power to the internal voltage required by the system.

All EX8216 components are hot-swappable, and all central functions are available in redundant configurations, providing high operational availability by allowing continuous system operation during maintenance or repairs.

Routing Engine ModuleThe EX8216 Routing Engine module supports control and management plane functionality with an integrated Routing (QJLQH�WKDW�IHDWXUHV�D�����*+]�3RZHU3&�SURFHVVRU�ZLWK���gigabytes of DRAM and 2 gigabytes of flash storage. A dedicated front-panel RJ-45 Gigabit Ethernet port on the Routing Engine module supports out-of-band system management and monitoring, while an external USB port allows easy uploading and storage of software images, configuration files, and logs. Direct console access is available through a dedicated serial port, while an auxiliary console interface can support remote modem access to the switch.

The EX8216 switch’s Routing Engine is based on the same field-proven hardware architecture used by Juniper Networks routers, bringing the same carrier-class performance and reliability to the EX8216 that Juniper’s routers bring to the world’s largest service provider networks. The Routing Engine’s central CPU performs all system control functions and maintains hardware forwarding table and routing protocol states for the EX8216 switch. Dedicated hardware on the Routing Engine module supports chassis management functions such as environmental monitoring, while communication between Routing Engine modules and individual line cards takes place over a dedicated internal Gigabit Ethernet out-of-band control interface.

EX8216 Switch FabricThe switch fabric for the EX8216, distributed across eight rear-accessible switch fabric modules, serves as the central non-blocking matrix through which all network data passes. All eight SFMs in the EX8216 are always active, providing ample capacity to deliver line-rate Layer 2 and Layer 3 switching on all ports for packets of any size. If one switch fabric module were to fail, the remaining modules gracefully load-balance the data traffic to maintain line-rate performance on all 10-Gigabit ports without dropping packets. The SFMs are hot-swappable and field-replaceable, enabling failed units to be easily replaced without service interruption.

The eight active, load-sharing switch fabric modules collectively deliver up to 320 Gbps (full duplex) of packet data bandwidth per line-card slot, providing sufficient capacity to support future 100-Gigabit Ethernet deployments without requiring any forklift upgrades or changes to the EX8216 chassis. The EX8216 backplane connector system is designed to support switch fabric bandwidth of more than 12.4 Tbps—enabling the capacity of the EX8216 to potentially more than double in the future.

PowerThe EX8216 chassis contains six power supply bays, providing complete flexibility for both provisioning and redundancy. Each EX8200 AC power supply delivers 3,000 watts (W) of power at KLJK�OLQH�����$�DW�����9��WR�WKH�FKDVVLV��7KH�(;�����DOVR�VXSSRUWV�a 2,000/1,200 W power supply for high/low-line operation. The EX8200 AC power supplies are more than 90 percent efficient at a wide range of loads, minimizing building power requirements and reducing overall power consumption. These power supplies are interchangeable across the EX8200 line, simplifying maintenance and sparing.

Although only two power supplies are required for basic EX8216 configuration and power-up, the six power supply bays provide the capacity required to power all possible line-card configurations, and to support N+1 or N+N power redundancy to protect against both component and line input failures. The actual number of power supplies required depends on the combination of line cards installed and the desired level of redundancy (see table). For example, 9,600 W is required to support a chassis fully populated with 128 10-Gigabit Ethernet ports, while 9,000 W will support a mix of 10-Gigabit Ethernet and Gigabit Ethernet line cards.

Features and BenefitsHigh AvailabilityThe EX8216 switch delivers a number of high availability features to ensure uninterrupted, carrier-class performance, and also includes an extra slot to accommodate a redundant Routing Engine module. When a second Routing Engine module is present, it serves as a backup in hot standby mode, ready to take over in the event of a master Routing Engine failure. If the master fails, the integrated Layer 2 and Layer 3 graceful Routing Engine switchover (GRES) feature of JUNOS Software ensures the seamless transfer of control to the backup, maintaining uninterrupted access to applications, services, and IP communications.

Carrier-Class Operating SystemThe EX8216 runs the same JUNOS Software used by the EX3200 and EX4200 lines of switches, as well as the Juniper Networks routers that power the world’s largest and most complex networks.

By using a common operating system, Juniper Networks delivers a consistent implementation and operation of control plane features across all products. To maintain that consistency, JUNOS adheres to a highly disciplined development process that uses a single source code, follows a single quarterly release train, and employs a highly available modular architecture that prevents isolated failures from bringing down an entire system.

These attributes are fundamental to the core value of the software, enabling all JUNOS-powered products to be updated simultaneously with the same software release. All features are fully regression-tested, making each new release a true superset RI�WKH�SUHYLRXV�YHUVLRQ��FXVWRPHUV�FDQ�GHSOR\�WKH�VRIWZDUH�with complete confidence that all existing capabilities will be maintained and operate in the same way.

Simplified Management and OperationsA range of system management options are available for the EX8216 Ethernet switches.

The standard JUNOS CLI provides the same granular management capabilities and scripting parameters found in all JUNOS-powered devices. The EX8216 switches also include the integrated J-Web management tool, an embedded device manager that allows users to configure, monitor, troubleshoot, and perform device-level maintenance on individual switches via a browser-based graphical interface. In addition, integrated JUNOScript Automation tools provide early detection and automatic resolution of potential problems related to the operating system.

Juniper Networks Network and Security Manager provides system-level management across all EX8200, EX4200, and EX3200 lines of Ethernet switches, as well as other Juniper Networks products deployed throughout the network—all from a single console.

Finally, performance data from EX8216 switches can be exported to leading third-party management systems such as +3�2SHQ9LHZ��,%0�7LYROL��DQG�&RPSXWHU�$VVRFLDWHV�8QLFHQWHU��where it can be combined with management data from other network components to provide a complete, consolidated view of network operations.

In addition, the EX8200 line supports Juniper Networks Advanced Insight Solutions (AIS), a comprehensive set of tools that enable Juniper Networks Technical Services to automate the delivery of tailored, proactive network intelligence and support services.
